Public Beliefs About The Preventability Of Unintentional Injury Deaths, Deborah C. Girasek
Public Beliefs About The Preventability Of Unintentional Injury Deaths, Deborah C. Girasek
Uniformed Services University of the Health Sciences
This report is based upon the results of a national random digit dialed telephone survey in which 943 adults were queried. Subjects reported the proportion of deaths due to motor vehicle crashes, falls, fires/burns, drowning and poisoning that they felt were preventable. On average, respondents believed that 56% of ‘fatal accidents’ were preventable; as were 62% of motor vehicle crash deaths, 53% of fall deaths, 67% of drownings, 62% of fire/burn fatalities and 70% of accidental poisonings. Logistic regression models predicting preventability beliefs differed according to the type of injury event in question, but socio-economic status and perceived alcohol involvement …
Absence Of All Components Of The Flagellar Export And Synthesis Machinery Differentially Alters Virulence Of Salmonella Enterica Serovar Typhimurium In Models Of Typhoid Fever, Survival In Macrophages, Tissue Culture Invasiveness, And Calf Enterocolitis, Clare K.

In this study, we constructed an flhD (the master flagellar regulator gene) mutant of Salmonella enterica serovar Typhimurium and compared the virulence of the strain to that of the wild-type strain in a series of assays that included the mouse model of typhoid fever, the mouse macrophage survival assay, an intestinal epithelial cell adherence and invasion assay, and the calf model of enterocolitis. We found that the flhD mutant was more virulent than its parent in the mouse and displayed slightly faster net growth between 4 and 24 h of infection in mouse macrophages. Conversely, the flhD mutant exhibited diminished …

Correlates of patient satisfaction at varying points in time were assessed using a survey with 2-week and 3-month follow-up in a general medicine walk-in clinic, in USA. Five hundred adults presenting with a physical symptom, seen by one of 38 participating clinicians were surveyed and the following measurements were taken into account: patient symptom characteristics, symptom-related expectations, functional status (Medical Outcomes Study Short-Form Health Survey [SF-6]), mental disorders (PRIME-MD), symptom resolution, unmet expectations, satisfaction (RAND 9-item survey), visit costs and health utilization. Physician perception of difficulty (Difficult Doctor-Patient Relationship Questionnaire), and Physician Belief Scale. Immediately after the visit, 260 (52%) …
Tsc13p Is Required For Fatty Acid Elongation And Localizes To A Novel Structure At The Nuclear-Vacuolar Interface In Saccharomyces Cerevisiae, Sepp D. Kohlwein, Sandra Eder, Chan-Seok Oh, Charles E. Martin, Ken Gable, Dagmar Bacikova, Teresa Dunn

The TSC13/YDL015c gene was identified in a screen for suppressors of the calcium sensitivity of csg2Δ mutants that are defective in sphingolipid synthesis. The fatty acid moiety of sphingolipids in Saccharomyces cerevisiae is a very long chain fatty acid (VLCFA) that is synthesized by a microsomal enzyme system that lengthens the palmitate produced by cytosolic fatty acid synthase by two carbon units in each cycle of elongation. The TSC13 gene encodes a protein required for elongation, possibly the enoyl reductase that catalyzes the last step in each cycle of elongation. The tsc13 mutant accumulates high levels of long-chain bases …
Mutation Of The Gene Encoding Cytotoxic Necrotizing Factor Type 1 (Cnf1) Attenuates The Virulence Of Uropathogenic Escherichia Coli, Karen E. Rippere-Lampe, Alison D. O'Brien, Richard Conran, Hank A. Lockman

Cytotoxic necrotizing factor type 1 (CNF1) is a 115-kDa toxin that activates Rho GTPases and is produced by uropathogenic Escherichia coli (UPEC). While both epidemiological studies that link CNF1 production by E. coli with urinary tract disease and the cytopathic effects of CNF1 on cultured urinary tract cells are suggestive of a role for the toxin as a UPEC virulence factor, few in vivo studies to test this possibility have been reported. Therefore, in this investigation, we evaluated the importance of CNF1 in a murine model of urinary tract infection (UTI) by comparing the degree of colonization and damage induced …

This study investigated whether soluble paracrine factors mediated Salmonella-induced IL-8 expression in polarized model intestinal epithelia. We found that the basolateral media of model epithelia that had been apically infected with Salmonella typhimurium for a short period (10 minutes) could activate IL-8 secretion in virgin model epithelia, demonstrating that a proinflammatory factor (PIF) was indeed present. Initial characterization found that PIF was a heat-stable protein with a molecular mass of about 50 kDa that acts on the basolateral, but not apical, surface of model intestinal epithelia to elicit IL-8 secretion. PIF was not present in the media of model …
